在Linux平臺下，想在Oracle資料庫的SQL*PLUS的命令列提示符下，利用鍵盤上的上下箭頭，調出歷史執行的SQL命令，可以考慮採用rlwrap這一開源工具。

現，簡單記錄一下安裝過程（Red Hat Enterprise Linux as 5.4環境）。以前在4版本的作業系統上安裝時很順利，就不再記錄。

①解壓並安裝rlwrap工具:

	[root@server1 ~]# tar -zxvf rlwrap-0.30.tar.gz

	[root@server1 rlwrap-0.30]# ./configure

	......

	checking for tgetent... no

	checking for tgetent in -lcurses... no

	checking for tgetent in -lncurses... no

	checking for tgetent in -ltermcap... no

	configure: WARNING: No termcap nor curses library found

	checking for readline in -lreadline... no

	configure: error:

	You need the GNU readline library(ftp://ftp.gnu.org/gnu/readline/ ) to build

	this program!

	[root@server1 rlwrap-0.30]#

報錯！提示需要安裝readline-devel-5.1-1.1.i386.rpm包。

② 安裝readline-devel-5.1-1.1.i386.rpm 包：

		[root@server1 ~]# rpm -ivh readline-devel-5.1-1.1.i386.rpm
	

		warning: readline-devel-5.1-1.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
	

		error: Failed dependencies:
	

		libtermcap-devel is needed by readline-devel-5.1-1.1.i386
	

		[root@server1 ~]#

又報錯提示缺失libtermcap-devel包！

繼續安裝：
[root@server1 ~]# rpm -ivh libtermcap-devel-2.0.8-46.1.i386.rpm

		warning: libtermcap-devel-2.0.8-46.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
	

		Preparing...                ########################################### [100%]
	

		1:libtermcap-devel       ########################################### [100%]
	

		[root@server1 ~]# rpm -ivh readline-devel-5.1-1.1.i386.rpm
	

		warning: readline-devel-5.1-1.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
	

		Preparing...                ########################################### [100%]
	

		1:readline-devel         ########################################### [100%]
	

		[root@server1 ~]# cd rlwrap-0.30
	

		[root@server1 rlwrap-0.30]# ./configure
	

		checking build system type... i686-pc-linux-gnu
	

		checking host system type... i686-pc-linux-gnu
	

		checking for a BSD-compatible install... /usr/bin/install -c
	

		checking whether build environment is sane... yes
	

		checking for a thread-safe mkdir -p... /bin/mkdir -p
	

		checking for gawk... gawk
	

		checking whether make sets $(MAKE)... yes
	

		............
	

		............
	

		configure: creating ./config.status
	

		config.status: creating Makefile
	

		config.status: creating doc/Makefile
	

		config.status: creating src/Makefile
	

		config.status: creating doc/rlwrap.man
	

		config.status: creating distribution/rlwrap.spec
	

		config.status: creating config.h
	

		config.status: executing depfiles commands
	

		Now do:
	

		make (or gmake)  to build rlwrap
	

		make check       for instructions how to test it
	

		make install     to install it
	

		[root@server1 rlwrap-0.30]#
	

③ 根據執行執行，make,make install:

		[root@server1 rlwrap-0.30]# make
	

		make  all-recursive
	

		[root@server1 rlwrap-0.30]# make install
	

		Making install in doc
	

		make[2]: Leaving directory `/root/rlwrap-0.30'
	

		make[1]: Leaving directory `/root/rlwrap-0.30'
	

		[root@server1 rlwrap-0.30]#
	

④ 修改oracle 使用者的配置檔案，

		[oracle@server1 ~]$ pwd
	

		/home/oracle
	

		[oracle@server1 ~]$ vi .bash_profile
	

在其中，新增類似配置資訊：
alias sqlplus='rlwrap sqlplus /nolog'

⑤至此，oracle在SHELL提示符下，只需要執行sqlplus就可以進入SQL*PLUS的命令列提示符，並且可以利用鍵盤的上下箭頭調出之前執行過的歷史命令。

這是在RHEL 5.4版本的作業系統上安裝時的簡單記錄，而之前沒遇到過類似的問題，故簡單記錄之。

即先安裝libtermcap-devel-2.0.8-46.1.i386.rpm

然後安裝 readline-devel-5.1-1.1.i386.rpm

最後安裝rlwrap工具包。
